Please continue your efforts in Krishna Consciousness with great determination. Yes, Patience is is a qualification in the successful execution of devotional service. So study our literatures, discuss philosophical points and problems with your God-brothers, and especially chant regularly sixteen rounds daily without offense and go on Sankirtana. We must always remember that chanting of Hare Krishna Mahamantra is our life and soul.
